What is the Seattle Portland rivalry really like? I've heard rumblings about it but I highly doubt it's anything like Calgary Edmonton - trust they hate everything Edmonton in Calgary it's Springfield Shelbyville times a million... Do Seattle and Portland share any teams? NFL for instance?

The only thing we've ever shared in terms of sports Rivalries were The Sonics/Blazers in the NBA and the Sounders/Timbers in Soccer (Pre MLS for most of it)
